The permissible stress in axial tension in steel member on the net effective area of the section shall not exceed the following value ($${{f_y}}$$ is the yield stress)

A fillet-welded joint of $$6$$ $$mm$$ size is shown in the figure. The welded surfaces meet at $$60$$ - $$90$$ degree and permissible stress in the fillet weld is $$108$$ $$MPa.$$ The safe load that can be transmitted by the joint is

The maximum tensile stress at the section $$X$$ - $$X$$ shown in the figure below is

The components of strain tensor at a point in the plane strain case can be obtained by measuring longitudinal strain in following directions.
